Input the energy in joules, time duration in seconds and click the Calculate button to obtain

energy in watts.## How to convert joules to watts?

### Joules to watts calculation formula

P=The power P in watts (W)E=The energy E in joules (J)

t=The time duration t in seconds (s):

**P(in Watts) = E(in Joule) / t(seconds)**

**watt(w) = joule(j) / second(s)**

**Let's take an Example**

Find out the power(P) consumption of an electrical circuit where energy(E) is 100 joules for time period of 5 seconds in the circuit

P(W) = 100J / 5s = 20W
